BARBERS HCLIPPER.

Specification of Letters Patent.

Patented July an, 191?.

Application filed rebruary 1t, 1917. Serial No. 148,710.

To all whom it may concern:

Be it known that I, VINonNzo DIORIO, asubject of the Kin of Italy, and a resident of the borough of %3ronx, county of Bronx, city and State of New York, have invented certain new and useful Improvements in Barbers Hair-Clippers, of which the followhe main object of my invention is to automatically guide the clipping mechanism away from the surface being treated in such manner that a gradual and uniform increase of distanceis attained, resulting in a prescribed curvature of trim as hereinafter set forth,the invention consisting in the specific construction and arrangement of parts described and claimed, and the distinctive feature being the use of a contact roller,

. actuating gear, screw and spring mechanism by which the bearing plate is forced apart from the shearing mechanism by the passage under pressure of the roller over the surface under treatment, and the automatic return to normal position assured as soon as the implement is removed from said surface, or the pressure relaxed.

In the accompanying drawings,

Figure 1, is a side elevation of my improved hair clipping device, my auxiliary Surface bearing plate being shown as spaced apart from the clipping mechanism, as in use, 00-w', representing the surface traversed; r

Fig. 2, is a side elevation of the clipper head with the auxiliary bearing plate closed, as when not in use;

Fig. 3, is a top view of the clipper head;

Fig. 4. a view of the under side thereof;

Fig. 5, is a section taken upon planes of line 5-5, Fig. 3; I

Fig. 6, is a diagram illustrating the function of my improved hair clipping device.

The hair clipping mechanism is essentially the same aS that heretofore used consisting of-the base plate B, secured rigidly to the spring socket b, which is formed integral with the fixed handle I) the clipping blade 0, reciprocated by the hand lever c; and the cap plate a, secured to the fulcrum stud b", by the thumb nut b -the hand lever c, be-

ing actuated against the resistance of a spring in the socket b, in the usual manner.

The new parts are the auxiliary bearing plate p, the contactual roller r, (see particu larly Figs. 4, and 5) mounted on the under side thereof, the screw shafts s, s;-,torsion springs t, t, and'adjuncts. Thus the auxillary bearing plate 10, is formed with two'perpendicular posts p, p, slidably mounted in recesses formed for them in the base plate B, cutter blade 0, and cap plate a, and it is also preferably formed with a series of parallel slots 17", (Fig. 4) through which hair clippings may escape from between the base plate B, and said auxiliary bearing plate p.

The lower ends of the screw shafts s, 8, are mounted in the rear portion of the auxiliary bearing plate p, and carry bevel gears s, s, which mesh with corresponding bevel gears 1", 1", secured to the journals of the contactual roller 7", which latter is mounted in bearlngs 19 39 on the under side of the auxiliary bearing plate p. The screw shafts s, 8, pass through openin s formed for them in the base plate B, an their'screw-threaded upper ends s s engagewith stationary nut arms a, a, integral with the cap plate a.

Encircling each screw shaft 8, between the base plate B, and the stationary nut arms a, a, is a coiled torsional spring 6, secured at its lower end to the base plate B, and at its upper extremity to said screw shaft 8. The tendency of these springs is constantly to turn and hold said screw shafts s, in normal position, as in Fig. 2, with the auxiliary plate 10, closed against the base plate B. When the roller '7', is pressed against a resistant surface, as say, m, 00, Figs. 1, and 6, and made to traverse the same, its bevel gears 7 r, cause the shaft gears s, s, to rotate the screw shafts s, 8, against the resistance of the coiled torsional springs 25, t, thereby causing the stationary nuts a, a, to force the screw shafts s, s, downward, so as to separate the auxiliary bearing plate 39, from' the base plate B, the guide posts 39, p, admitting of this movement and insuring the-proper alinement of parts. As a result .the distance between the auxiliary bearing late p, and the cutting blade 0, will be gradiially increased as the -roller 7', advances over the resistant surface, causing the clipping to be done in a curve,

and clipping the halr in gradually and uniformly increased lengths as indicated diagrammatically in Fig. 6, in which as, repre- .sents the starting point and m, the finish.

When the roller 1', is relieved from pressure and removed from the resistant surface at, w, the springs t, t, immediately rotate the screws shafts 8, s, in the oppositev direc tion, causing the stationary nuts (1, a, to retract the said screw shafts s, 8, until the auxiliary plate p, again rests against the base plate B, and the parts are restored to normal condition and relationship, ready for the next clipping operation, when the same action will be repeated if the roller 1*, is forcibly made to traverse a resistant surface. Thus, supposing the curves m, w, in Fig. 6, to represent the contour of the back of the neck and lower rear portion of the head of a person having a hair trim, it is obvious that the graduation of clip from practically nothing at as, to a maximum of length at m, may be readily effected with as much ease as an ordinary close crop would be made by the usual barbers clippers as heretofore known and used.

This implement is designed for use exclusively for the purpose designated; 71. 6., that of trimming the hair at the back of the head and neck, or for effecting a graduated short cut for the whole head if desired, starting from-close to the skin at the lower rear and sides of the head and gradually extending to a maximum of length of hair above or at top and all this may be expeditiously accomplished without special skill on .the part of the operator because my graduatlng apparatus is automatic in action and requires no more time nor care than that involved in an ordinary hair crop close to the skin as made by barbers clippers now in use, the scope of which is limited, as be fore intimated to the function of cutting off the hair near its roots.

What I claim as my invention and desire to secureby Letters Patent is,

1. In a hair trimming device of the character designated, in combination, hair clipping mechanism, a contactual roller, a gear mounted thereon, a screw shaft on which is mounted a gear meshing with that mounted on said roller, a fixed nut engaging said screw shaft, and a coiled torsional spring attached at one extremity to said screw shaft and at the other extremity to a fixed part, for the purpose described.

2. In a hair trimming device of the character designated, in combination, hair clipping mechanism, a bearing plate, a contactual roller mounted thereon, a screwshaft on which is mounted a gear meshing with that mounted on said roller, a fixed nut engaging said screw shaft, and a coiled torsional spring attached at one extremity to said screw shaft and at the other extremity to a fixed part, for the purpose described.

3. In a hair trimming device of the character designated in combination, hair clipping mechanism, a bearing plate mounted thereon, and formed with a guide post positioned in recesses formed for it in the structure of said hair clipping mechanism, a contactual roller mounted on said bearing plate, gears rigidly connected with said contactual roller at each end thereof, screw shafts engaging with fixed nuts on the casing of the hair clipping mechanism, gears on the lower ends of said gear shafts meshing with the gears on the ends of the contactual roller, and torsional springs coiled around said screw shafts and attached thereto and to fixed parts, for the purpose described.

4. In a hair trimming device of the character designated, in combination, hair clipping mechanism, a bearing plate mounted thereon and formed with two guide posts positioned in recesses formed for them in the structure of said hair clipping mechanism, a contactual roller mounted on said bearing plate, gears rigidly connected with said contactual roller at each end thereof, screw shafts engaging with fixed nuts on the easing of the hair clipping mechanism, gears on the lower ends of said gearshafts meshing with the gears on the ends of the contactual roller, and torsional springs coiled around said screw shafts and attached thereto and to fixed parts, for the urpose described.
